You can start by looking on major fanfiction websites like Fimfiction. It has a large collection of My Little Pony - related fanfictions, and there's a good chance you'll find some 'Shining Armor Hurt' ones there.
There could be a fanfiction where Shining Armor's hurt is more emotional. Maybe he faces some sort of betrayal from a comrade he trusted. This type of story can explore his inner strength and how he copes with such a difficult situation. In the fanfiction, he might initially feel lost and broken, but then gradually find his way to heal and forgive.
I really enjoy Chrysalis and Shining Armor fanfics. They often explore unique relationships and scenarios. Some fanfics might focus on Chrysalis' complex character and how she could interact with Shining Armor in different ways, like in a world where she tries to reform. It's fascinating to see how authors play with their personalities.
A fanfiction could also be about their childhood memories. Maybe there was an event in their past that they both remember differently, and as they talk about it, it reveals more about their characters and how they've grown over the years. It could be a heartwarming story full of family bonds and the magic of reminiscing.
One interesting fanfiction could be about Twilight and Shining Armor's childhood adventures that were never shown in the original series. Maybe they had a secret magical place they used to go to and explore together.
One common theme is friendship. Spike and Shining Armor often form a strong bond in these fanfictions. Another theme could be adventure, like going on quests together. Protection is also a theme, with them protecting each other or the places they love.
Another theme is loyalty. Shining Armor's loyalty to Twilight and vice versa. They are always there for each other no matter what. This can be seen in fanfictions where one of them gets into trouble and the other drops everything to help.
It can start with a conflict. For example, King Sombra might be causing trouble for Shining Armor's kingdom. But then, through a series of events like a shared quest or a mutual acquaintance's intervention, they start to see each other in a different light.
First, you can start by thinking about the relationship between Shining Armor and Twilight. What kind of dynamic do you want to show? Is it a story of brother - sisterly love, or more of a mentor - mentee kind of thing? Then, come up with a basic plot. It could be as simple as them going on an adventure together.
Social media groups related to My Little Pony can also be a good source. For example, on Facebook or Reddit, there are groups where fans discuss all aspects of the show, including sharing fanfiction. However, you need to be a bit more careful on these platforms as the quality control might not be as strict as on dedicated fanfiction websites.
